The Senate and the House are in session this week, and then out next week for the Fourth of July holiday. Among the lingering issues they’ll deal with — other than slogging through the appropriations process — is the disappeared e-mails of former Internal Revenue Service official Lois Lerner (more on that here). Oversight Chairman Darrell Issa (R-Calif.) has two hearings scheduled on that and then turns his attention to management issues that have plagued the Environmental Protection Agency.
